Description
Given a closed polygon boundary domain in the plane, this X-Function generates interior mesh by delaunay triangulation and resamples data points at the mesh nodes.
Examples
1. Import Resample.dat in \\Samples\Data Manipulation folder.
2. Set column D as X column, then column D, E will be used as boundary curve.
3. Type xy_resample -d in the command window to bring up the dialog.
4. Set column A, B as Input and D, E as Boundary Vertices. Enter 50 to the Number of Points on Edge box.
5. Click OK to run the X-Function.
Algorithm
